近年来，各种涂层[1]相继出现，如仿生粘附[2]、逐层组装[3]、界面聚合[4]等。其中，生物启发式方法以其环境友好、效率高、可控性强、多功能性强等优点而备受关注。尤其是贻贝激发的多巴胺涂层已经被广泛研究。尽管聚多巴胺(pDA)易于施涂于基材上，可沉积于各种材料上，并具有许多潜在的应用用途，但多巴胺的高成本可能会阻碍某些实际应用。与贻贝启发涂料多巴胺相比，植物多酚启发涂料不仅具有与多巴胺涂层相同的优点，如对各种底物的强附附性，在温和条件下自发聚合[6]，而且具有自己独特的优势，如价格低廉，原料来源广泛，环保[7]。

In recent years, various coatings have emerged one after another, such as biomimetic adhesion [2], layer by layer assembly [3], interface polymerization [4], etc. Among them, biological heuristic methods have attracted much attention due to their advantages such as environmental friendliness, high efficiency, strong controllability, and strong versatility. Especially the dopamine coating stimulated by mussels has been widely studied. Although polydopamine (pDA) is easy to apply to substrates, can deposit on various materials, and has many potential applications, the high cost of dopamine may hinder some practical applications. Compared with the mussel inspired coating dopamine, plant polyphenol inspired coatings not only have the same advantages as dopamine coatings, such as strong adhesion to various substrates and spontaneous polymerization under mild conditions [6], but also have their own unique advantages, such as low price, wide source of raw materials, and environmental protection [7].

In recent years, various coatings [1] have appeared one after another, such as bionic adhesion [2], layer-by-layer assembly [3], interfacial polymerization [4] and so on. Among them, biological heuristic method has attracted much attention because of its advantages of environmental friendliness, high efficiency, strong controllability and strong versatility. In particular, the dopamine coating excited by mussels has been widely studied. Although poly-dopamine (pDA) is easy to be applied to the substrate, can be deposited on various materials, and has many potential applications, the high cost of dopamine may hinder some practical applications. Compared with mussel-inspired paint dopamine, plant polyphenol-inspired paint not only has the same advantages as dopamine coating, such as strong adhesion to various substrates and spontaneous polymerization under mild conditions [6], but also has its own unique advantages, such as low price, wide source of raw materials and environmental protection [7].
